The Cloudflare testing page uses defineWorkersProject from @cloudflare/vitest-pool-workers/config. That export, along with poolOptions, was removed in @cloudflare/vitest-pool-workers 0.13.0 (the Vitest 4 release), and the package has since been renamed to @cloudflare/vitest-plugin (npm marks the old name as deprecated). With current packages the documented vitest.config.ts doesn't load:

Error: Missing "./config" specifier in "@cloudflare/vitest-pool-workers" package

This PR:

• switches the example to the cloudflareTest() plugin and wrangler.jsonc, which match the create-hono Workers template and Cloudflare's docs
• imports env from cloudflare:workers, since env from cloudflare:test is deprecated
• replaces the See Also links: the examples folder link was a 404, and the Miniflare 2 migration guide no longer applies
• updates the package name in the testing guide and on the Workers getting started page, which now links to this example

I copied the snippets from the page into a fresh npm create hono@latest Workers project (hono 4.13.16, @cloudflare/vitest-plugin 1.6.0) and the test passes on Vitest 4.1.12 and 5.1.0. pnpm build and the Prettier check also pass.
